Kim Kardashian: I Have Had Botox (VIDEO)

The Kardashian women appeared on 'Nightline' Monday night and talked with ABC's Cynthia McFadden about plastic surgery, posing for Playboy and the seven-figure vibrator endorsement they turned down. Here are some highlights, scroll down to watch.

Kourtney on her boob job:
"I have had breast implants, but it's so funny 'cause it's not a secret, I could care less. It's so funny because the 'before' picture that they [In Touch magazine] showed was after I had my boob job, so I'm like, they should have written 'before Mason' and 'after Mason.' Like my boobs have like tripled since breastfeeding."

Kim on her natural boobs and Botox:
"Trust me honey, if I take this bra off you will tell me I need to get them done. I'm totally not against plastic surgery. ... I've tried Botox before. That's the only thing that I've done."

Kris on encouraging daughter Kim to do Playboy:
"I thought it was a good idea. I thought that so many iconic women have done Playboy. And I thought, you know for Marilyn Monroe... She wanted to do it, too. I mean, I didn't force her to go do Playboy."

Kim on reports that she regretted posing for Playboy:
"When I said that comment, I had said...'I'm sorry that I did Playboy then, when I was in the shape that I was in. Not the shape that I'm in now. Because I had lost 15 pounds. ... So it kind of got misconstrued a little bit."
